Inverted repeated sequences in yeast nuclear DNA.
The inverted repeated sequences (foldback DNA) of yeast nuclear DNA have been examined by electron microscopy and hydroxyapatite chromatography. Of the inverted repeat structures seen in the electron microscope, 34% were hairpins and 66% had a single stranded loop at the end of a duplex stem. The number average length of the repeat was 0.3 kb and the single stranded loop was 1.6 kb. It is estim...
متن کاملSynapsis-mediated fusion of free DNA ends forms inverted dimer plasmids in yeast.
When yeast (Saccharomyces cerevisiae) is transformed with linearized plasmid DNA and the ends of the plasmid do not share homology with the yeast genome, circular inverted (head-to-head) dimer plasmids are the principal product of repair. By measurements of the DNA concentration dependence of transformation with a linearized plasmid, and by transformation with mixtures of genetically marked pla...
متن کاملAltered replication and inverted repeats induce mismatch repair-independent recombination between highly diverged DNAs in yeast.
Replication, DNA organization, and mismatch repair (MMR) can influence recombination. We examined the effects of altered replication due to a mutation in the polymerase delta gene, long inverted repeats (LIRs) in motifs similar to those in higher eukaryotes, and MMR on intrachromosomal recombination between highly diverged (28%) truncated genes in Saccharomyces cerevisiae. A combination of alte...
متن کاملCentromeres of the Yeast Komagataella phaffii (Pichia pastoris) Have a Simple Inverted-Repeat Structure
Centromere organization has evolved dramatically in one clade of fungi, the Saccharomycotina. These yeasts have lost the ability to make normal eukaryotic heterochromatin with histone H3K9 methylation, which is a major component of pericentromeric regions in other eukaryotes. Following this loss, several different types of centromere emerged, including two types of sequence-defined ("point") ce...
متن کاملTRANSNASAL ENDOSCOPIC APPROACH FOR SINONASAL INVERTED PAPILLOMA
Inverted papillomas of the nose and paranasal sinuses are uncommon neoplasms, characterized by their tendency to occur and by their association with malignancy. In the past decade there has been a trend toward the use of endoscopic surgical techniques in the management of these tumors. This article presents the results of a prospective study of24 patients with inverted papilloma resected by...
